About Proxima Fusion

Fusion will be one of the greatest breakthroughs of this century. Proxima Fusion is working to develop power plants via optimized stellarators, devices that form magnetic cages for high-energy matter. Proxima is the first-ever spin-out company from the Max Planck Society Institute for Plasma Physics, which built and operates the most advanced stellarator on the planet, W7-X. Research over the past decade has now set the stage for Proxima to leverage modern optimization tools and design capabilities, and accelerate fusion. With W7-X reaching high-performance in continuous operation, uniquely among fusion concepts, Proxima Fusion is catalyzing the creation of a new fusion ecosystem in Europe. Connecting partners from industry and academia, the Proxima Fusion founding team, coming together from the Max Planck Society, MIT and Google, is now entering the race for fusion energy to turn stellarators into economically viable fusion power plants.

Proxima Fusion Raises €20M Seed to Accelerate Timeline to Fusion Power

Less than one year from its €7.5M pre-seed round, the first Max Planck fusion spin-out has delivered on its vision of simulation-enabled stellarator design. New funding supports expansion of the world-class team in Munich and its public-private partnerships in Europe to build on existing momentum. Proxima Fusion directly builds on €1.3B of public investment in the ground-breaking W7-X experiment in Germany. Munich, Germany, April 10, 2024 – Proxima Fusion, the first spi

A European champion for fusion: Proxima Fusion spins out of the Max Planck Institute for Plasma Physics

Munich, May 30th 2023 – Proxima Fusion, a fusion start-up that is designing fusion power plants based on the stellarator concept, completed its pre-seed fundraising of €7m. The fundraising is co-led by Plural and UVC Partners, and joined by High-Tech Gründerfonds (HTGF) and the Wilbe Group. Proxima Fusion is the first spin-out from the Max Planck Institute for Plasma Physics (IPP). The startup was founded by former scientists and engineers from the Max Planck IPP, MIT, and Google
